METTLER TOLEDO Micro pH Electrodes

Introduction

The METTLER TOLEDO Micro pH Electrodes deliver accurate pH measurement for extremely small sample volumes and narrow containers. Designed for applications involving microplates, vials, cuvettes, test tubes, and biological samples, these high-performance electrodes combine precision with exceptional reliability. Compatible with METTLER TOLEDO Seven Excellence, Seven Compact, and other compatible meters, they also support Intelligent Sensor Management (ISM) technology for automatic calibration recognition and simplified sensor management, making them an excellent choice for research, pharmaceutical, clinical, and quality control laboratories.

pH electrodes designed for small sample volumes or for measuring in small containers.

• For use with METTLER TOLEDO Seven Excellence and Seven Compact meters as well as other brands. (Connection cable is not included; sold separately.)
• Intelligent Sensor Management (ISM) electrodes capture and save calibration data, which is then automatically recognized by the meter once connected.
• Capture electrode calibration and results with LabX software, designed for advanced data management and 21CFR part 11 regulatory compliance.
• Compatible with InMotion Autosampler to automate measurement and cleaning of up to 303 samples.
